A transverse wave on a string has an amplitude of 16cm, a wavenumber of 5.7m-1, and a frequency of 39Hz. What is the propagation speed of that wave?
(a) 6.84 m/s
(b) 39.2 m/s
(c) 43 m/s
(d) 6.24 m/s
(e) 6.88 m/s
This is a question on my physics study guide packet and while we have done wave problems in the past it was never anything like this. First: can someone explain what a wavenumber is. Second: what is propagation speed. Third: which equation should I be using. I thought maybe xmcos(ωt+Φ) but I don't know what the phase angle would be. I'm very confused, I would just like to have a basic understanding of what this is asking.
